Re: 93 Grand Cherokee-Won't Start in Cold
The Cherokee has a ballast resistor for the fuel pump too.

Hi Dennis,
The twelve volts during cranking, just mean the solenoid's bypass
is working properly.
I'd give it the normal tune-up, plugs, wires, cap, and rotor,
seeing you eluded to a misfire.

Hi all.
<side note, html is icky> :)
Going to go through a few ideas.
Ignition issues including misses at speed.
Bad sparkplug
bured out wire
cracked cap
burned through rotor
Worn out distributor. (can you move the rotor from side to side or
is there a lot of oil in the bottom of the distributor)
If yes, you need a new distributor.
http://members.***.net/wilsond/distributor/
I'm almost betting your rotor has burned a hole in it and
the spark is going through the distributor to ground.
More things to check.
Does the fuel pump turn on when the ignition key goes to run?
Is the fuel rail pressure up to 32psi?
(an R-12 gauge works well to test pressure)
http://members.***.net/wilsond/Fixes...-test-port.jpg
Have you cleaned the Idle Air Passage in the TB?
(usually associated with rough idle though)
http://members.***.net/wilsond/tb/tb.html
ESD relay (emergency shutdown relay) gone bad. This will
prevent a start, but it also prevents the fuel pump from
cycling. (Relay center behind the battery)
The diagnositcs page on my site might help.
Gotta run.

Re: 93 Grand Cherokee-Won't Start in Cold
Doug,
Lot of great info and I really like your style on your Web site. I want a
supercharger now!
Going to check the distributer in the morning. If you missed it, I finally
got started up. I think through a combination of pumping the gas and holding
it to the floor. Started really rough but then almost immediately settled
down to smooth. Drove it, parked it, started it, did errands and honey-do's
and it had no problem.
I'll check fuel pressure. I have a couple R-12 gauges around here somewhere.
We'll see what happens in the morning.
Would the ESD relay behave this way as it's failing? You know, what with
cold weather starting problem I mean.
Thanks for all your help and access to a great site.
Denny

Lot of great info and I really like your style on your Web site. I want a
supercharger now!
Going to check the distributer in the morning. If you missed it, I finally
got started up. I think through a combination of pumping the gas and holding
it to the floor. Started really rough but then almost immediately settled
down to smooth. Drove it, parked it, started it, did errands and honey-do's
and it had no problem.
I'll check fuel pressure. I have a couple R-12 gauges around here somewhere.
We'll see what happens in the morning.
Would the ESD relay behave this way as it's failing? You know, what with
cold weather starting problem I mean.
Thanks for all your help and access to a great site.
Denny
